A fixing component 7 for easy replacement of the lower mold 8 is provided on the lower end of the fixed support plate 81. The lower mold 8 is placed on the upper end of the fixed support plate 81. Guide columns 5 are fixedly installed at the four opposite corners of the upper end of the pre-pressing worktable 1. Movable plates 6 are slidably sleeved on the outer sides of the four guide columns 5. A fixed support plate 81 is fixedly installed on the upper end of the movable plate 6. A fixing component 7 for easy replacement of the upper mold 4 is provided on the lower end of the fixed support plate 81. The upper mold 4 is provided on the lower end of the movable plate 6.

[0023] In a specific embodiment, according to the shape and size of the interior trim, a suitable upper mold 4 and lower mold 8 are selected and installed on the movable plate 6 and fixed bracket plate 81 respectively by the fixing component 7. The interior trim is placed on the lower mold 8, the device is started, the movable plate 6 drives the upper mold 4 to move downward and close with the lower mold 8, and pre-pressure is applied to the interior trim. The guide column 5 ensures that the up and down movement of the movable plate 6 is smooth and vertical, avoids the upper mold 4 and the lower mold 8 from shifting or tilting, and ensures the accuracy of pre-pressure forming.

[0024] Please refer to Figures 1 to 3 As shown, as a technical optimization of this utility model, a top plate 3 is fixedly installed on the upper end of each of the four guide columns 5. A hydraulic mechanism 2 is fixedly installed on the upper end of the top plate 3 near the center. The lower end of the hydraulic mechanism 2 is fixedly connected to the upper end of the fixed bracket plate 81. Through holes 83 are opened through the upper end of the fixed bracket plate 81.

[0025] In a specific embodiment, the automotive interior parts to be processed are placed on the lower mold 8, and their position is adjusted to align with the mold cavity. The device is started, and the movable plate 6 is pushed downward along the guide column 5 by external force such as a hydraulic system, which drives the upper mold 4 to approach the lower mold 8. The upper mold 4 and the lower mold 8 close, and pre-pressure is applied to the interior parts to make them initially formed.

[0026] Please refer to Figures 1 to 5 As shown, in one technical optimization of this utility model, the fixing component 7 includes side plates 71. One side of each side plate 71 is fixedly installed on one side of the inner wall of the fixing bracket plate 81. A connecting plate 72 is fixedly sleeved on the lower part of the opposing sides of the two side plates 71. A bearing sleeve 75 is fixedly sleeved inside each connecting plate 72. A rotating stud 74 is fixedly sleeved on the inner ring of each of the multiple bearing sleeves 75. A fixing stud 73 is rotatably connected to the outer side of each of the multiple rotating studs 74. A fixing stud 73 is rotatably connected to the outer side of each of the multiple fixing studs 73. Inside the lower mold 8 and the upper mold 4, a plurality of rotating studs 74 are respectively fixedly mounted on the lower ends of a drive wheel 78, a first transmission wheel 710 and a second transmission wheel 712.

[0027] In a specific embodiment, the lower mold 8 and the upper mold 4 are placed at corresponding positions on the movable plate 6 and the fixed support plate 81. The servo motor 76 is started to drive the rotating shaft 77 and the drive wheel 78 to rotate. When the drive wheel 78 rotates, it drives the first transmission belt 79, which in turn drives the first transmission wheel 710 to rotate. When the first transmission wheel 710 rotates, it drives the second transmission belt 711, which in turn drives the second transmission wheel 712 to rotate. The transmission system drives the rotating stud 74 to rotate, and the rotating stud 74 rotates within the inner ring of the outer ring of the bearing sleeve 75. The fixed stud 73 engages with the internal threads of the upper and lower ends of the mold, further driving the fixed stud 73 to rotate. Gradually, the lower mold 8 is fixed on the fixed support plate 81, and the upper mold 4 is fixed at the lower end of the movable plate 6, thereby realizing the replacement of the upper mold 4 and the lower mold 8 of the pre-pressing device.

[0028] In use, the automotive interior trim part to be processed is placed on the lower mold 8, and its position is adjusted to align with the mold cavity. The device is activated, and external force, such as a hydraulic system, pushes the movable plate 6 downward along the guide column 5, causing the upper mold 4 to approach the lower mold 8. The upper mold 4 and the lower mold 8 close, applying pre-pressure to the interior trim part to initially shape it. The lower mold 8 and the upper mold 4 are then placed in the corresponding positions on the movable plate 6 and the fixed support plate 81. The servo motor 76 is activated, driving the rotating shaft 77 and the drive wheel 78 to rotate. When the drive wheel 78 rotates, it drives the first transmission belt 79. This further drives the first transmission wheel 710 to rotate. When the first transmission wheel 710 rotates, it drives the second transmission belt 711, which in turn drives the second transmission wheel 712 to rotate. Through the transmission system, the rotating stud 74 rotates, and the rotating stud 74 rotates within the inner ring of the outer ring of the bearing sleeve 75. The fixing stud 73 engages with the internal threads of the upper and lower ends of the mold, further driving the fixing stud 73 to rotate, gradually fixing the lower mold 8 onto the fixing bracket plate 81, and fixing the upper mold 4 onto the lower end of the movable plate 6, thereby realizing the replacement of the upper mold 4 and the lower mold 8 of the pre-pressing device.
